Multi-striking surface golf putting stroke trainer

ABSTRACT

A multi-face putting stroke trainer has multiple striking faces. Each striking face is parallel to the shaft so that any selected striking face is perpendicular to the direction of the stroke. Any of the striking face may be selected for stroke training depending on the skill level for an individual.

FIELD OF THE INVENTION

[0002] This invention relates generally to the golf putting stroketrainer.

BACKGROUND OF THE INVENTION

[0003] The game of golf is generally known and has been around for manygenerations. It is a game of accuracy, wherein the accuracy is based onthe lowest score possible. The score is determined by the number ofstrokes required to place a golf ball in a cup which resides on aputting green.

[0004] There are many factors involved in reducing a golfer's score. Oneof the biggest factors involved in reducing the score is the use ofproper clubs, particularly the golf putter. Statistically, it is knownthat 42 percent of the total strokes come from putting. Although playerseven have a putter that is perfectly set up, there are many otherfactors that can cause a player to miss a putt. Of course, mis-reading abreak is one of the dominont factors in missing the hole. However,another dominent factors in missing the hole is not having a goodstroke. Without a proper stroke, a putter head can move off track ortilte during the back stroke or down stroke. Consequently, as putter'sthe striking surface strikes the ball, the ball is contacted outside ofthe sweet spot of the putter's striking surface or the putter's strikingsurface is not perpendicular to the aimed direction. Although the widthof the putter's striking surface is usually two to three times widerthan the diameter of the golf ball, the width of the sweet spot area ofthe putter's striking surface is much shorter than the diameter of thegolf ball. If the sweet spot is missed during the contact of the golfball, the putter head (and striking surface) is tilted and the ball'sinitial rolling direction is not same as the original aim. Therefore,striking the golf ball with the sweet spot area of the putter's strikingsurface is necessary to have a golf ball roll toward the intendedtarget. Striking the golf ball with the sweet spot of the putter is oneof hardest skills to gain without a special training aid. Novices oreven average handicap golfers have many difficulties in gaining theproper putting stroke because there are no good putting stroke trainerson the market today. Training is the way to gain the skill. Like anyother training, stroke training must have several steps to reach the toplevel of skill.

SUMMARY OF THE INVENTION

[0005] With the forgoing in mind, the present invention provides asimple stroke trainer to improve the putting stroke from the beginner tothe top level player. Then it is desirable to have a putting stroketrainer that has multi-striking surfaces, with each striking surface adifferent size in area. For example, a stroke trainer has a strikingsurface 1, striking surface 2, striking surface 3 and striking surface4. Striking surface 1 has the largest striking surface area and strikingsurface 4 has the smallest striking surface area. All striking faces areparallel to the shaft which insure that the striking face isperpendicular to the direction of the stroke. The bottom (sole) of thestroke trainer head which is the opposite side of the shaft hole has aspherical curveture so that it would not provide a sharp toe or heeledge. Otherwise a sharp edge could scraches the putting surfaceaccidentally. With this stroke trainer, beginners could start to usestriking surface 1 as the first step of stroke training. As their strokeskills improve, they could use striking surface 2, striking surface 3and striking surface 4. If he or she can use striking surface 4comfortably, then his or her skill in putting stroke will have reached aprofessional level and will eventually save many strokes when actuallyplaying.

OBJECT OF THE INVENTION

[0006] Besides addressing the matters and problems above, the mainobjects of the present invention are:

[0007] (a) to provide a multi-striking surface stroke trainer so that anindividual can select the striking surface to achive the level of stroketraining.

[0008] (b) to provide a stroke trainer to improve their stroke step bystep.

[0009] (c) to improve a golfer's putting accuracy and consistencythrough proper training.

DETAILED DESCRIPTION OF INVENTION

[0013] A multi-striking surface stroke trainer in this description hasmore than two striking surfaces. Although the total number of strikingsurfaces is not limited, only the four striking surface putting stroketrainer is described in this invention as an example.

[0014] FIGS. 1-3 illustrate the preferred embodiment of the presentinvention. A multi-striking surface stroke trainer 100 comprisesmulti-striking surface stroke trainer head 10, a shaft 20 and a grip 30.Head 10 has first striking surface 1, second striking surface 2, thirdstriking surface 3 and fourth striking surface 4 around the shaftinghole 5. The preferred position of the shafting hole 5 is such that theimaginary extended center line of the shafting hole 5 meet the center ofthe gravity of the head 10. The shafting hole 5 is parallel to all fourstriking surface 1, 2, 3, and 4. All four striking surface 1, 2, 3 and 4are perpendicular to the one imaginary bottom plane 8. Bottom surface 6has spherical shape curvature.

[0015] The weight of the multi-striking surface stroke trainer head 10is preferred to have a similar weight of the conventional putter headwhich is between 310 gram and 340 grams approximately. The firststriking surface I has the largest flat area. The second strikingsurface 2 has the second largest flat area. The s third striking surface3 has the third largest flat area. The fourth striking surface 4 has thesmallest flat area.

[0016] The actual size of the striking faces 1, 2, 3 and 4 are not alimiting factor of this invention. However, largest striking face 1 ismuch larger than the io smallest striking face 4. The spirit of thepresent invention being limited solely by the appended claims.

What is claimed is:
 1. A golf putter-stroke trainer comprising A trainer head, the trainer head comprising a plurality of striking faces The striking faces varying in size
 2. The golf putter-stroke trainer according to claim 1 wherein the trainer head is attached to a shaft
 3. The golf putter-stroke trainer according to claim 1 wherein the trainer head includes any metal or composite material
 4. The shaft according to claim 2 having a grip at its distal end
